Received messages sent from both the IMC and the ISC channels are collected by the IMC. The
IMC dispatches messages which have to be sent either to its own I
2
C interface or to the ISC for
transmission.
2.3.2 IPMC Standard Functions
The standard functionality of the Artesyn Embedded Technologies IPMC is available on the
IPMC of the ATCA-MF106. For detailed information, see the ATCA-MF106: Control via IPMI
Programmer’s Reference.
2.4 Power Supply
The shelf manager is powered by dual redundant -48 VDC to -60 VDC (rated voltage) from the
backplane connector.
The power supply of the shelf manager is compliant with the requirements of the PICMG 3.0
R3.0 (AdvancedTCA) specification. Each of the four power connections is separately fused.
Fuse rating is 1 A.
An EMI filter at the power input ensures conducted emission levels below EN 55022 class B.
2.4.1 Onboard and External Supply
The ATCA-MF106 has no provisions to switch off the power input. The board is powered
whenever the power is attached to the Centellis 2000 system (-40 VDC to -72 VDC).
An on-board DC/DC-converter supplies all onboard circuitry, and provides:
 3.3 V power supply to external circuits with a consumption of no more than 4 W
 3.4 V management power via the backplane pins
Output voltage is slightly above 3.3 V to compensate losses caused by ORing circuits, which
may be present at the external load.
The board satisfies the standby power limit of 10 W for AdvancedTCA FRUs, even when
supplying 4 W to external loads. Typical power consumption of the ATCA-MF106 board is 5 W.
